Sewage treatment device with sewage circulation treatment function

Abstract

The invention discloses a sewage treatment device with a sewage circulation treatment function. The device comprises a sewage treatment tank, a third water pump, a gas-liquid pressurizer, a purification tank and a filter tank, wherein the filter tank is arranged at the central position in the sewage treatment tank, a second water pump is fixed at the top end of the filter tank on one side of the third water pump, the gas-liquid pressurizer is mounted on one side, far away from the second water pump, of the top end of the filter tank, the purification tank is arranged in the sewage treatment tank on one side, far away from the third water pump, of the gas-liquid pressurizer, a water quality detector is arranged at the bottom of the purification tank, a pressurizing pipe is installed at thetop of the side, close to the filter tank, of the purification tank, a reflux pipe is installed at the end, close to the purification tank, of a drainage pipe through a three-way pipe, and heating plates are fixed to the bottom end and the two side walls in a settling tank. According to the sewage treatment device, the working efficiency of the sewage treatment device is improved, the safety of water quality in use is ensured, and secondary pollution of the sewage treatment device to the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device with a sewage circulation treatment function. Background technique [0002] Water is the source of life. In the past, most of the sewage generated in rural areas and cities was simply treated in sewage treatment plants, and even a small part of urban sewage and industrial sewage were directly discharged into rivers, which once made groundwater and rivers, lakes and seas It is seriously polluted, which affects the survival of all kinds of animals, and as the social development is not as good as the 21st century, there are fewer and fewer pure water sources on the earth, and the protection of water resources is gradually being valued by people. In our country, every city There are many sewage treatment plants to purify the sewage generated every day, and then transport the qualified water to rivers or urban systems for recycling, including domesti...

[0002] Water is the source of life. In the past, most of the sewage generated in rural areas and cities was simply treated in sewage treatment plants, and even a small part of urban sewage and industrial sewage were directly discharged into rivers, which once made groundwater and rivers, lakes and seas It is seriously polluted, which affects the survival of all kinds of animals, and as the social development is not as good as the 21st century, there are fewer and fewer pure water sources on the earth, and the protection of water resources is gradually being valued by people. In our country, every city There are many sewage treatment plants to purify the sewage generated every day, and then transport the qualified water to rivers or urban systems for recycling, including domestic water from residents, polluted surface water, factory wastewater, etc., these water Including many large particle components, the sewage treatment is directly carried out, which greatly increases the difficulty of sewage treatment. The sewage treatment in the prior art is realized through water collection wells, regulating pools, and disinfection pools. First, due to insufficient air tightness, the purification reaction is not sufficient. , often need to repeat the purification many times, which greatly wastes manpower and material resources. Second, it is separated from the water quality testing work, which makes it difficult to ensure the safety of the discharged water. Third, the precipitated substances lack timely treatment. Easy to cause secondary pollution to the environment
